NYSTROM, oroHIoAGo, ILLINOIS CAR-VWINDYOWCONSTRUCTION epplieationffiledJanuary 15,1927. Seria1rNo. 1 61 39Qinvention relatesetoan' improved window construction for railroadpassenger cars, streetcars andinterurban cars; the inventionhaving forits object the provision 5 of a construction, controllable by thenoonpant of the seat or berthwhereby suitable v'e'ntilation and ingressof air may be obtained; while at the same time providing-aconstructionwhereb'y a maximum vision is 10 obtained in a 'givenwindo'wopening and a suitable avenue vis providedto permit communicationbetween'the occupant of'the car and an individual on the outsidewithoutnecessitating opening of the outside window;

15 The objectsand' advantages oii my-invention will be readilycomprehended from the following detailed description j of theaccompanying drawings, wherein I Figure 1 is an inside elevatlon of asection i j 20 of railroad car provided with my improved 7windowconstruction;'with the floor shown in section and the underfram'eomitted.

The invention also contemplates means wherebyathe outer window ispivotally secured in place; whilethe" inner window involves meansoperable from the car interior wherebyeasy and positive operation of theof the upper end of awindowscreen em- Figure 7 is a sectional view"taken sub-- inner window by the occupant "may behad;

f As my invention ismore especially intended, for use in connection'Withfsleeping cars, 5 the exemplification discloses a'section of asleeper, namely with the opposing seats being "shown at 15, "15, in'Figure'lyarr'angedi as usual, adj acent; to, a pair of windows gener-.

allyindic'ated at 16-, 16 in said ffigure, with 6 the Windowatthe'left'bein sho'wnpartially raised and the opening there eneathprovided with a suitable mesh screen indicated at 17. -InFigure' 3, 18andj19 represent portions ofthe outer andinner car walls, spaced apartas usual and'provided With an openingeto I receive my improved windowframe construcnon 20 ,'h'aving an opening in thetop to per- 7 mit Pgerofth inner window-sash' 2l when the latter israised; r

"The inner windowesash 21 at one side is l preferably" providedjwith arack 22'and a' bearing rolle'r 23; while'the opposite side of the sashis also shown provided with a bearing roller 24 which is preferablysupported by an upwardly disposed. projection 25' formed on theupper endof the inner: sash to receive any thrusts that may be encountered int'he'operation of thewi'ndow. The side portion of the frameQO, which ispreferably of metal, is formed to provides, 7

"sash receiving groove'or channel 26 of'de pth suiiicient to receive thebearing rollers" asiwell v as a portion of the side members of'the winedow-sash. The. frame 20' is also formedto provide the intermediatebentportion whereby an abutting shoulder 27 is provided for the outervsash 28, which is thereby maintained in spaced relation with the innersash-21; I

' The car interior" side of the window-frame 20 is also it'or'mediwith asmall vertically disposed groove 1 or socket-at- 29 to provide aslide-way fortheside frames of the windowscreen 17 the grooves29 beingarranged-in close/proximity to the window slide-way, as shown in Figure5.

I The frame member 20 at the right Figure 5, at a'point coincident with;the chan'nel26, and preferably adjacent to the upper end ofthe-innerwindowesa h 21; is provided rwitha;

tion su suitable opening for passage of a segment or portion of a pinion30 in order that the latter may mesh with the rack 22 formed on the adjacent side of the inner window sash, The pinion is mounted in the carside wall by means of a suitable bracket as at 31 in Figure 5; with thejournalof the pinionextending through to the, car-interior wherel'QliSiOIHH-Bd to receive a crank 32.

It is apparent that the inner window 21' may be easily raisedor1loweredJoyapropertie-v eration of the crank 82 and that the rollers23,

24 will hold the sash against lateral move ment and cause the window toslide easily.

The lower part or ledge :of the window frame comprises a hollow orchambered nor- 601133, The extremeends of this chamber are open at '34;34 to the car exterior; the
